The Jabra Sport Pulse Wireless Earbuds is retailing in Singapore for S$298. It is a Bluetooth 4.0 wireless in-ear earphones with a built-in in-ear heart rate monitor. According to the specifications, the heart rate monitor has a 99.2% accuracy when compared to a medical electrocardiogram (ECG) machine. I can’t really verify it since I don’t have other heart rate monitor to test with.
